I don't get it really, even if those are similar in some ways they are completely different tracks. I make electronic music and it is almost certain that anything you "create" will follow an existing pattern and that precious melody we think is new and "ours" will only differ a bit from what has been already made. There isn't much "new" things around if nothing at all "Was Michael Hoening a fraud" that's a bit disrespectful taking in account the data you are showing us.

Did you even listen to the examples? This is way too similar to be a coincidence.

According to the comments under one of the vids, Hoenig purchased the rights to use the Lifeforce theme. IF that's true, that would mean:1. Legally, it wasn't plagiarism, as he held the rights to use it, and2. It's certainly no coincidence - it was an intentional remake/remix.
